Genes affected

NOD2 (HGNC:5331): (nucleotide binding oligomerization domain containing 2) This gene is a member of the Nod1/Apaf-1 family and encodes a protein with two caspase recruitment (CARD) domains and six leucine-rich repeats (LRRs). The protein is primarily expressed in the peripheral blood leukocytes. It plays a role in the immune response to intracellular bacterial lipopolysaccharides (LPS) by recognizing the muramyl dipeptide (MDP) derived from them and activating the NFKB protein. Mutations in this gene have been associated with Crohn disease and Blau syndrome. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.014914691).
• BP6: Variant 16-50712175-C-T is Benign according to our data. Variant chr16-50712175-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 319462.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00285 (434/152388) while in subpopulation NFE AF = 0.00525 (357/68040). AF 95% confidence interval is 0.0048. There are 1 homozygotes in GnomAd4. There are 197 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High AC in GnomAd4 at 434 AD,Unknown gene.
